Letters Patent No. 60,308, dated December 4, 1866.

p SPEGIFIGATION. T0 ALL WHOM IT MAY CONCERN:

Be it known that I, WILLIAM M. WHITTAKER', of Wallingford, in the county of New Haven, and State of Connecticut, have invented a new improvement in Butter Dish; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and .which said drawingsfconsttute part of this specification, and L represent in Figure I, a side view of the dish, partially opened.

Figure 2, a top View, fully opened; and in Figures 3, 4, 5, and 6, `detached views and parts, to illustrate the construction and operation.

This invention relates to what is known as the revolving cover butter dish, and consists in the peculiar arrangement for attaching the cover to the dish so that it may be removed from the dish, when required, without entirely removing the pivot, as in the common construction.

To enable others to construct my improvement, I will proceed to describe the same as illustrated in the accompanying drawings:

A is the bowl, and P the cover,` of any Vdesired or known form or design. The bowl is formed so that the cover pivoted at C will swing between the outer and inner case of the bowl, as denoted in tig. 1, and so as to open entirely, ,as in iig. 2V Upon the cover I form earsa, as seen in figs. 2 and 4, and upon the bowl, corrcsi ponding ears C. (See figs. 2 and And through the ears C, I pass a pivot d, provided on its outer end with a knob D, or other convenience, for turning the pivot. The inner end of the pivot is fornicdilat and thin, and so as to form a shoulderhf. (See figs. 5 and 6.) And the ear C is formed with a notch, c, into which the shoulderfmay be drawn, as, see iig. so that the inner endof the pivot will comedlushlywith the inner surface of the ear. This notch s is formedy directly below the pivot, sothat only when the'shoulderfis perpendicular it can be withdrawn, and so that when turned away from thesaid notch, as in fig. 3, the pivot cannot be withdrawn. In each of the ears a upon the cover a mortisc is formed, as seen in iig. 4, to receive the flat end of i thepivot, 'so that when thecover4 is placed in its proper position, and the pivots pressed inward, the {lat-ted ends of the pivot enter the mortise in the ears a, so that by turning the piv'ot thefcoverwill also be turned. Were the mortises in the ears a and the notchesl in the ears C exactly perpendicular vand corresponding, the pivots could be withdrawn whenthe cover was closed, which would beV an objection to this manner of pivoting. To avoid this I make the mortise in the ears a diagonal, so that they will correspond to the notches in the ears C only when the cover is partially open, as seen in gs. 1 and 4, so that .when the cover is open or closed, thc pivot cannot be withdrawn, and therefore is not liable to displacement; but when it is desired to remove the cover for lany purpose, raise the cover until the mortise in the ears a corresponds. to the notch in theears C, whatever that position may be; then the pivots may be withdrawn, and the cover reniov'ed.

I Having, therefore, thus fully described my invention, what I claim as new and useful, and desire to secure by Letters Patent, is Y The combination of the pivot d and the ears C and a, when constructed and arranged, so as to operate substantially in the manner herein set forth. p

WM. M. WHITTAKER.
